General Physical Description
The Power Feed 10M Single Wire Feeder is a modular
wire feeder, consisting of two components - a wire
drive and a control box - are available assembled as
a bench unit or as a boom system. High speed, high-
ly reliable digital cables connect the components
together and to the Power Wave power source.
The Power Feed 10M Single Wire Feeder system has
the ability to connect multiple wire feeders to one
power source, use the same power source to weld in
two different locations (not simultaneously), or load a
different electrode on each feeder to eliminate change
over time.
The powerful four roll wire drive system sets the indus-
try standard for ease of use. Its patented design allows
for tool-less change out of wire guides and drive rolls
greatly reducing set up time.

Transferring welding settings from one wire feeder to
another is accomplished with a common palm com-

coupled to a Power Wave welding power source,
the result is a welding system with absolutely supe-
rior arc performance.
